r/LocalLLaMA·medium signal

Tesslate released OmniCoder-v2-9B, an upgrade to their Apache 2.0 coding agent model built on Qwen3.5-9B's hybrid architecture. Trained on 425K+ agentic coding trajectories with 262K native context (extensible to 1M+). Early community reports show improvements over v1 in multi-step reasoning and error recovery. At 9B parameters, it's positioned as the best open-source coding agent model runnable on consumer hardware.
